The spontaneous breaking of time-translation symmetry has led to the discovery of a new
phase of matter: the discrete time crystal. Discrete time crystals exhibit rigid subharmonic …

“Quantum sensing” describes the use of a quantum system, quantum properties, or quantum
phenomena to perform a measurement of a physical quantity. Historical examples of …

Realizing a long coherence time quantum memory is a major challenge of current quantum
technology. Until now, the longest coherence-time of a single qubit was reported as 660 s in …

Quantum noise is the key challenge in Noisy Intermediate-Scale Quantum (NISQ)
computers. Previous work for mitigating noise has primarily focused on gate-level or pulse …

The magnetic fields generated by spins and currents provide a unique window into the
physics of correlated-electron materials and devices. First proposed only a decade ago …

Markovian approximation is a widely-employed idea in descriptions of the dynamics of open
quantum systems (OQSs). Although it is usually claimed to be a concept inspired by …

Quantum computing is a game-changing technology for global academia, research centers
and industries including computational science, mathematics, finance, pharmaceutical …

The scalable application of quantum information science will stand on reproducible and
controllable high-coherence quantum bits (qubits). Here, we revisit the design and …

Presently, one of the most ambitious technological goals is the development of devices
working under the laws of quantum mechanics. One prominent target is the quantum …

Dynamical decoupling (DD) is perhaps the simplest and least resource-intensive error-
suppression strategy for improving quantum computer performance. Here we report on a …
